I know, it took me some time to realize it was alters... Especially as I didn't remember what happened, so I didn't know it was anything extreme, and then bam I find out that I beat up some people.
I am basically not sure how many alters I have, and 2 of them are not communicative much, one would be absolute panic, really crippling reaction, I'd call it the flight response alter, and the other would be manic fighting, which I'd call fight response. With one I go into panic and am unable of anything, I'd just crouch or something somewhere or whatever and endure whatever is happening. Without remembering. I spent a lot fo time like that, and it's one of my main dissociation states. And the other, that doesn't come out as often would be the fight response, which will I guess try to protect me, and then wipe the memory, so I don't remember beating someone up even if it happened a minute ago... It's really wierd.
